Creating a variance column

Hi there, I am new to Domo and I have a question that I believe has an easy solution, however, I cannot figure it out. I have a table created to display Cost per load over the past three months. The formula for CPL is SUM(carrier pay
)/ SUM(Loads
). I want to have a column that displays the previous months CPL - Current months CPL and call it variance. I assume it requires a case statement stating if order ship date = previous month then previous CPL. However, I dont know how to write that.
Any advice or tips would be extremely helpful.

@ColinHaze You can accomplish this using case statements inside your sums. The LAST_DAY function can be used to transform dates to the last day of the month so you can compare months.
Current Month CPL
sum(case when LAST_DAY(`Date`) = LAST_DAY(CURRENT_DATE()) then `carrier pay` else 0 end) / sum(case when LAST_DAY(`Date`) = LAST_DAY(CURRENT_DATE()) then `Loads` else 0 end)
Prior Month CPL
sum(case when LAST_DAY(`Date`) = LAST_DAY(DATE_SUB(CURRENT_DATE(),interval 1 month)) then `carrier pay` else 0 end) / sum(case when LAST_DAY(`Date`) = LAST_DAY(DATE_SUB(CURRENT_DATE(),interval 1 month)) then `Loads` else 0 end)
Variance
— Prior Month (sum(case when LAST_DAY(`Date`) = LAST_DAY(DATE_SUB(CURRENT_DATE(),interval 1 month)) then `carrier pay` else 0 end) / sum(case when LAST_DAY(`Date`) = LAST_DAY(DATE_SUB(CURRENT_DATE(),interval 1 month)) then `Loads` else 0 end)) - — Current Month (sum(case when LAST_DAY(`Date`) = LAST_DAY(CURRENT_DATE()) then `carrier pay` else 0 end) / sum(case when LAST_DAY(`Date`) = LAST_DAY(CURRENT_DATE()) then `Loads` else 0 end))
